And it's what's called a topological invariant.

也一种拓扑不变量。

A topological insulator acts like both at the same time, which we used to think was impossible!

The topological properties of subatomic particles could also transform quantum computing.

亚原子粒子拓扑特性也可改变量子计算。

But in some exotic topological phases, the subatomic particles can become protected.

但一些奇异拓扑相中，亚原子粒子可受到保护。

Now you don't have to worry about what a topological qubit is.

现您不必担心什么拓扑量子位。

What's really weird--One really weird finding about these lobes is that they include topological maps.

真正奇怪——这些波瓣一个非常奇怪发现它们包含拓扑图。

We're taking a very different approach to our qubit, which is based on this topological qubit.

我们对我们量子比特采取了一种非常不同方法， 它基这个拓扑量子比特。

These topological qubits would be more stable, leading to more accurate computation and a better quantum computer.

这些拓扑量子位会更稳定，从而导致更准确计算和更好量子计算机。

Topological properties don't change when an object is gradually stretched or bent.

当对象逐渐拉伸或弯曲时，拓扑属性不会改变。

One example is called a topological insulator.

一个例子叫做拓扑绝缘体。

Nowadays, scientists are working to develop topological insulators, and some think they could be as important for future technologies as semiconductors are today.

当前，科学家们正致力研发拓扑绝缘体。其中有些人认为拓扑绝缘体对未来技术就像今天半导体一样重要。

But the Nobel Laureates discovered that topological properties do exist at the quantum level.

但诺贝尔奖获得者发现，拓扑性质确实存量子层面。

Thouless and the final winner, Duncan Haldane, are both also using topology to pave the way for a new kind of material: topological insulators.

索利斯及最后一位获奖者邓肯·霍尔丹都用拓扑学为一种新物质——拓扑绝缘体开辟了道路。

So this year's Nobel Laureates have pioneered some important research into molecular machines and topological materials, and it looks like there's a lot more on the horizon!

因此，今年诺贝尔奖获得者分子机器和拓扑材料方面开启了一些重要研究。而看起来还有更多研究即将露面。

So this year’s Nobel Laureates have pioneered some important research into molecular machines and topological materials, and it looks like there’s a lot more on the horizon!

因此，今年诺贝尔奖获得者率先开展了分子机器和拓扑材料一些重要研究，而且看起来还有更多！

Duncan Haldane, and Michael Kosterlitz won the award for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological.

邓肯·霍尔丹 (Duncan Haldane) 和迈克尔·科斯特里茨 (Michael Kosterlitz) 因发现即使最小尺度微观物质也能表现出宏观性质和拓扑相而获奖。

They then used their topological algorithm to figure out which areas were inaccessible by roads, then generated the most cost effective ways to build roads and connect them to outside services.

然后，他们使用拓扑算法找出哪些区域无法通过道路进入，然后生成最具成本效益方法来修建道路并将它们连接到外部服务。

The edge of such a topological insulator has perfect electron transport: no electrons travel backward, no energy is lost as heat, and the number of conducting pathways can even be controlled.

这种拓扑绝缘体边缘具有完美电子传输：没有电子向后移动，没有能量作为热量损失，甚至可控制导电通路数量。
